Cylindrical roller bearings: Bearings in which the cylindrical rollers and raceways are in line contact. The internal structure of cylindrical roller bearings uses rollers arranged in parallel, and spacers or isolation blocks are installed between the rollers to prevent the tilt of the rollers or the friction between the rollers, effectively preventing the increase in rotational torque.

Applications of cylindrical roller bearings: large and medium-sized electric motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, reduction gearboxes, rolling mills, vibrating screens, and lifting and transportation machinery, etc.
